Straws and gauze: the first 24 hours

The two most precise instructions in all of the published guidance both belong to the first day, and both are about the same thing.

Written Sep 24, 2026Documents re-read Sep 24, 2026

Two instructions, one mechanism

Almost everything published about the first day after an extraction is vague on purpose — soft food, gentle rinsing, take it easy. Two instructions are not vague at all, and they are the two worth memorising.

The first is the ADA's: avoid drinking through a straw for 24 hours. The second is the NHS's: if you get bleeding, press the area for at least 10 minutes with a clean cloth or piece of cotton wool. Both are exact, both belong to day one, and both exist for the same reason — the ADA says the mouth fills in the bone where the tooth root was through the formation of a blood clot, and the NHS says a blood clot forms over the wound, which helps it to heal.

The first day, from the two published do-and-do-not lists
  1. First hourPressure, not curiosityThe NHS's instruction on bleeding is at least 10 minutes of pressure with a clean cloth or piece of cotton wool. Lifting the pad to check interrupts the thing you are waiting for.
  2. First eveningNo suctionThe ADA's straw instruction runs for 24 hours. Its neighbouring instructions are not to smoke and not to rinse your mouth vigorously — the same mechanism, three different ways.
  3. SwellingCold, and a phone callThe ADA's extraction page says that if you experience swelling, apply a cold cloth or an ice bag and call your dentist right away. Both halves of that sentence are the instruction.
  4. CleaningEverything except the siteYou can brush and floss the other teeth as usual, the ADA says, but not the teeth next to where the tooth was removed. The NHS says to clean your other teeth carefully, avoiding the affected area.
  5. TravelOnly if you were not sedatedThe NHS's driving intervals are 48 hours after a general anaesthetic and 24 hours after a sedative injection. They are published figures, not suggestions.

Nothing here is invented. Each row restates a sentence from a page named on our facts file.

The gauze question, answered as precisely as it is published

The published instruction is the NHS's, and it has four components worth separating: press, the area, at least 10 minutes, with a clean cloth or piece of cotton wool. People routinely get the third one wrong, because ten minutes with a mouthful of gauze is longer than it sounds and the temptation to check at four minutes is strong. Checking restarts the clock on the only process that is going to end the bleeding.

What is not published is how many times to repeat it, or at what point repeating it stops being the right response. The urgent list at the top of this page is the published answer to that second question: bleeding that does not stop is its first line, without a number of attempts attached.

We publish no packing technique, no substitute material and no home remedy. The ADA's instruction for swelling is to apply a cold cloth or an ice bag and call the dentist right away; nothing in either source asks a patient to put anything into the socket.

Why a straw, specifically

Because the concern is suction, not the drink. That is also why the same lists contain "do not smoke" and "do not rinse your mouth vigorously" — three activities that share one physical idea. Once you see the shared idea, the odd-looking rules stop being arbitrary and start being a single instruction wearing three hats.

It also means the boundaries of the straw rule are exactly where the document puts them: 24 hours, and drinking through a straw. Neither source extends it to fizzy drinks, to temperature, or to using a bottle rather than a glass. The drinks page is careful about exactly which of those are published and which are not.

Sleeping, which everybody asks and nobody publishes

Neither the NHS page nor the ADA page we read says anything about how to sleep after an extraction — not about propping yourself up, not about which side, not about pillows. It is one of the most-searched aspects of the first night and one of the least documented, and we are not going to fill that gap with confident prose.

What the sources do give you for the first night is the same short list as for the first day: the pressure instruction if bleeding starts, the cold cloth and the phone call if swelling appears, nothing through a straw, nothing hot, nothing hard, and the urgent list for anything that does not fit.

What the first day is worth, in the documents that price it

One thing the fee schedules quietly tell you about day one: a visit whose only purpose is to settle dental pain has its own priced line, separate from the extraction. It is $79.43 in Louisiana, $55.00 in Illinois and $43.70 on the Arkansas adult row. Those are payer maximums rather than what a surgery charges, but they establish that being seen about pain is a billable event in its own right.

Against that, one payer explicitly deems it included. The Vermont Medicaid Dental Supplement's ten-day rule treats palliative treatment for pain within that window as included in the payment for the primary procedure and not reimbursed separately. Which of those two shapes your own surgery uses is worth asking on the day — the cost page sets out both.

A first day assembled only from published sentences

Everything below restates something quoted earlier on this page. It is set out as a sequence because that is how the day arrives, not because any document presents it this way.

  1. Leave with the out-of-hours number and the surgery's own instruction sheet. Where that sheet and this page disagree, the sheet wins.
  2. If you were sedated, do not drive — 24 hours after a sedative injection, 48 after a general anaesthetic, on the NHS's published figures.
  3. If bleeding starts, press the area for at least 10 minutes with a clean cloth or piece of cotton wool, without lifting it to check.
  4. If swelling appears, the ADA's instruction has two halves: apply a cold cloth or an ice bag, and call your dentist right away.
  5. Eat soft or liquid food. Nothing hot, nothing hard or crunchy, nothing that could lodge in the wound such as nuts or seeds.
  6. Nothing through a straw for 24 hours. Do not smoke. Do not rinse vigorously.
  7. Brush and floss the other teeth as usual, leaving the teeth beside the socket alone.

The things people do that no document suggests

Three habits account for most of the avoidable trouble on day one, and not one of them appears as advice anywhere in either source.

  • Checking. Lifting the pad every few minutes to see whether the bleeding has stopped is the commonest way of extending it, because the published instruction is ten minutes of uninterrupted pressure.
  • Investigating. Torches, mirrors, tongues and fingers all arrive at the same place, and the entire published instruction set is about leaving the site alone.
  • Swilling. Rinsing feels like cleaning, and both documents warn against doing it vigorously — the ADA says not to at all in the first few days unless you must, and every time the NHS mentions rinsing it qualifies the word with gently.

What you can eat while all this is going on is on the eating page.

Questions about the first day

How long do I keep the gauze in?

The NHS's published instruction is to press the area for at least 10 minutes with a clean cloth or piece of cotton wool if you get bleeding. It gives no number of repeats and no upper limit, and bleeding that does not stop is the first line of its urgent list.

When can I use a straw again?

The ADA's extraction page says to avoid drinking through a straw for 24 hours. That is the published interval, and it is one of only two precise timings in the whole of the first-day guidance.

How should I sleep?

Neither source we use says. It is among the most-searched questions about the first night and among the least documented, and rather than invent an answer we would rather point you at the surgery's own sheet.

Is some bleeding normal?

The ADA's page says that in most cases a small amount of bleeding is normal. The distinction the documents draw is not about quantity but about whether it stops: bleeding that does not stop is on the NHS's urgent list.

Can I brush my teeth that evening?

The ADA says you can brush and floss the other teeth as usual but not the teeth next to where the tooth was removed; the NHS says to clean your other teeth carefully, avoiding the affected area so you do not damage the stitches or the clot. Brushing and rinsing goes through both.
